(01. 28-2) This invention relates to improvements in apparatus for making tassel fringe.

Its object is to provide means and ways of producing such material rapidly and inexpensively.

Another object is to eliminate the waste attendant upon the manufacture of tassel fringe by such machines and methods as have been available heretofore.

These and other objects of the invention will appear in the following specification in which I will describe a machine which embodies my invention, the novel features of which will be set forth in appended claims.

Referring to the drawings,

Fig. 16 is a plan view of the lower forked die;

Fig. 17 is a plan view of or part of the binder with a superposed cross section of its core; and

Fig. 18 is a plan view of a, novel material made with the machine hereindescribed. This material is shown to the right of the line A A as a knitted structure especially designed to be made into tassel fringe. Between lines A A and B-B it has been modified by the addition of binders to certain of its parts and to the left of line BB the modified material has been severed into strips of tassel fringe.

Before specifically describing the parts and partof the tassel fringe making materialwhich is shown to the right-of the line A A in Fig.

- longitudinal strands of thread 23, as at 24, and

operation of the machine, I will describe the back to the edge of tape 20. Spaced from the strand or strands 22 are other strands 25 similarly looped around the strand or strands 23, as at 26.

From the inner edge of the other tape, 30

- one or more strands 32 extend at right angles midway between the strands 22 and 25, are looped around longitudinal strands 33, as at 34, and then run back to thetape 30.

A warp rope 40 of a plurality of parallel strands of yarn or the like, extends back and forth intermediate the tapes 20 and 30 in the manner shown. At a point 4|, in transverse alinement with the strands 22 and spaced from the tape 20, this warp rope isdoubledupon itself. Longitudinal threads 21 run th ough the loop thus formed, between the strands 22 and around the outside of the doubled warp strand to tie these parts together closely. In the same transverse line, but spaced inwardly from the longitudinal strands 2'1, are longitudinal strands 28 which tie one group of warp yarn to one of the strands 22 and the adjacent group of warp yarn to the other strand 22 and hold these two groups together, as at 42, in such a position that they abut in a line between the strands 22.

From this point one of the groups of warp yarn extends diagonally away from the strands 22 to the longitudinal strands 33 which tie the group together, as at .43. Thence, this group of warp yarn extends at right angles to the tapes to the longitudinal strands 23 which tie the group together, as at 44.

This group of warp yarn then extends diagonally to longitudinal strands 38 which tie it and one of the strands 32 together, as at 45. The group then passes around longitudinal strands 31, around which it is looped and tied together with the strands 32, as at 46. Thence it runs back to the longitudinal strands 38 which tie it and the other strand 32 together, as at 41. The ties at 45 and 41 are symmetrically disposed in relation to the transverse strands 32. The warp rope extends diagonally to the longipassing over rods 14.

gitudinal strands 25 which tie it and the strands 25 together at 48, in the manner described. This construction is continued to form a tassel fringe making material M of indefinite length. This material is made on a knitting machine. of known construction, but the material is new.

By means of an apparatus which will be described hereinafter, binders 88 are clamped around the parts of the warp rope between the longitudinal strands 21, 28 and between the longitudinal strands 31, 38. The material will then be in the condition in which it is illustrated in Fig. 18 between the lines AA and BB.

On the line BB the materiakis severed longi tudinally by a cutter -I58 between the longitudinal strands 23 and 33. -When the longitudinal strands are removed, two rows of --tassel fringe F and F will result, as shown to the left of line BB, in Fig. 18. The inner parts of the strands 22, 25 will be embedded in and form parts of the tufts of the tassels formed on tape 28 and the inner ends of strands 32 will be in the tufts of the tassels formed on tape 38. The only material lost in making this tassel fringe is the longitudinal strands, for which waste material may be used, and the small loops 22A and 32A which run over the longitudinal strands 23 and 33, respectively. o

The apparatusfor applying the binders to the material M and severing it longitudinally, comprises a frame 58 which supports a table I and the other parts of the mechanism. 52 is a reel on which the material M is wound. The material is passed under 'a guide rod and tension device 53 to a double sprocket 54, over rollers 55, 55 and the severed material passed over a double sprocket 51. The teeth of the double sprockets engagethe parts of the material M which is between the longitudinal strands 21, 28 and 31, 38. The sprockets 54 are mounted on a shaft 58 and the sprockets 51 are mounted on a shaft 59.

68 is a drive shaft which is connected by a chain 6| and suitable sprockets to rotate an intermediate shaft 52. 63 is a chain which'connects shaft 62 to drive a countershaft 64. Crank arms 65 near the ends of countershaft 64 impart. a reciprocating movement to connecting rods 56, the corresponding ends of which are connected to'the crank arms and their other ends are connected to rock levers 61 which'are loosely mounted on the end of shaft 59. Pawls 68 on these rock 1 ers engage ratchet gears 89 aifixed to shaft 5 By this mechanism a step by step rotation is imparted to the sprockets 51.

This step by step rotation is transmitted to' shaft 58 and sprockets 54 by sprockets 18 on shaft 59, sprockets H on shaft 58 and interconnecting chains 12..

The parts of the driving mechanism thus de-- scribed are so proportioned and arranged that they bring the part of material M which is in transverse alinement with its strands 22 up to the line CC of Fig. 1, then the part of the material which is in alinementwith its strands 32 up to the line CC, then the part which is in alinement with strands 25 up to the line C C, et'seq.

As the material M is moved along, its tape thread 82.

by a pin I I5 in the frame edges 28 and 38 are drawn down to the table by resilient guide strips 13.. Its parts adjacent'its tape edges are raised slightly above the table by The material is under sprockets 54, 51 and this arrangement keeps it' under lateral tension.

The binder material 88. s shown in detail in Fig. 17, comprises a flat wire '8I covered with a A supply of this binder material is wound on two-spaced reels on a common axis. Aside elevation of these reels is shown in Fig. 1 and portions of the binding material are shown in Fig, 2, to illustrate their spaced relation. Each of these strips of binding material passes through a. curved guide 84 and between a pair of feed rollers 85, 86 which are geared together and through a horizontal straight guide 84A. The rollers 86 are afiixed to alinedshafts 81 to which are affixed ratchet gears 88. Rocker arms 89 are pivotally mounted on the shafts 81. They carry pawls 98 which engage the ratchet gears 88.

. 9I are connecting rods between these rocker arms and crank pins 92 on opposite ends of an upper shaft 93. Sprocket gears 94 on shaft 93 areconnected by chains 95 with similar sprocket. gears 96 on the intermediate shaft 62 to drive the upper shaft 93. The crank pins 92 are angularly spaced 90 apart so that when one of the pawls 98 moves forwardly the other moves in has a flat body portion I8I vertically slidable in a stationary frame I82, (Figs. 5, 6 and 7).

Pins I83 project laterally from the sides of the body I8I of this cutter and guide and are engaged by springs I 84 which raise it so that its upper end I85 engages a cylindrical portion of a cam 91 aflixed to the upper shaft 93. Side pieces I86, I81 are afiixed to the body I8I on its lower portion. The ends of these side pieces are grooved transversely, as at I88.

An eccentric part 98 of cam 91 forces the cutter and holder downwardly. As its side pieces reach the binder 88, an edge I89 of side piece I 86 passes over a shear block I89A through'which the lginder projects and severs the binder at this pom The severed end of the binder at this time rests upon an anvil I I8 and in the grooves I88 of the side pieces I86 and I81. The anvil, as shown in Fig. 4 projects laterally from aplunger III which is telescopically guided in a laterally movable swinging frame I I2, pivotally supported at II3. A spring II4 forces the plunger upwardly in the frame I I2. Its upward movement is limited which passesthrough a slot H6 in the plunger.

I28 is an upper die which lies against the body I8I of the cutter and guide and slides independently in the stationary frame I82. Pins I23 which project from its sides are engaged by springs I24 which raise it so that its upper end rests I against the cylindrical part of the cam 91. The lower part I26 of this upper die is narrow and slides between the sideflpieces I86 and I 81. Its lowerend I21 is rounded to conform to the anvil II8. An eccentric part 98A of cam 91 engages the top I 25 of this upper die and imparts to it a downward movement slightly behind that of the cutter and holder engages the binder 88 at the time it is severed and holds it against the anvil II8.

From that point the cutter and holder I88 and the upper die I28 move downwardly together to the positions in which they ar s n in g. 13.

I88, so that its end I21 portion I38.

At this time the end I21 of the upper die holds the center of the severedpart of the binder 80 firmly against the anvil III) and the side pieces I06, I 01 bend it i'nto'the shape of a flaring staple, as is shown in Fig. 13. Y

During this part of the operation, a lower forked die I30 is moving upwardly. The lower die comprises a body portion I3I which slides in vertical stationary guides I32. Pins I33 which project laterally from it are engaged by springs I34 which force it downwardly to bring its end I35 into engagement with the cylindrical part of a cam I40 aflixed to the intermediate shaft 62. The lower cam is raised by an eccentric part'I4I of cam I40.

I36 is the forked part of the lower cam. It is aflixed to the body portion I3I and is constructed to form a pocket having parallel walls I31 joined at their lower ends by a semi-circular Inclined walls I39 converge into the parallel wall I31. Central grooves I42 of sufficient width to receive the binder 80 are cut in the walls I39 and I31. These grooves terminate at the center of the semi-circular portion I38 where they curve upward, as shown at I43,

I44 into the surface which forms the semi-circular portion. (See Figs. 12 and 16.)

As the lower die moves upwardly, its forked part I36 embraces that part of the material M which is in its path, such as one of the portions designated by N in Figs. 13 and 18. This is a part of the material between the longitudinal strands 21, 28 and in symmetrical alinement with certain of the transverse strands, such as those designated by 25. The relative position of the parts as thus described is shown in Fig. 13.

The lower die finally moves up to the position in which it is shown in Figs. 14 and 15. During its final movement the upper die I26 moves to its Fig. 14 position, carrying with it the anvil .I I0, moved against the action of its spring I I4, with the severed portion of the binder between its end I21 and the anvil. The ends of the binder enter the groove I42 and are brought into parallelism by the plane of the walls I39.

When the upper die reaches this Fig. 14 position the end of its spring I24 contacts a beveled cam II1 on the swinging frame II2 (Fig. 4) to force the frame over tothe other side of the vertical and to pull the anvil IIO out of the binder.

The groove I42 has sufficient depth to permit the binder to pass outside of the portion N of the material M as the upper die continues to move downwardly to its Fig. 15 position. During this, its final downward movement, two functions are performed,-the portion N is squeezed together between the end I21 of the upper die and the semi-circular part I38 of the lower die into the condition in which it is shown at N in Fig. 15, and the ends of the binder are bent upwardly and outwardly into the warp material by the curved portions I43, I44 of the slot, as shown at 80A and 80B. Thus, the binder not only encircles the compressed warp strands and retains them in this condition, but the ends of the binder are embedded in the warp strands so that its covering thread 82 cannot unwind. After this operation the cutter and holder I00, the upper die I20 and the lower die I30 are returned to their initial positions by their respective springs.

At the time of this return movement of the parts mentioned, the material M is advanced a step to bring a portion of it, designated by 0 in Fig. 18, into alinement with another cutter and holder, upper die and lower die. The anvil I IOA is then in position to cooperate with the latter mentioned parts and the operation is repeated making the material in the condition in which it is shown between the lines A-A and 13-13 in Fig. 18.

I50 is an endless band cutter supported on an upper pulley I5I and a lower pulley I52, (Figs. 1 and 3).'-The latter is driven by a gear I53 in mesh with a gear I54 on the drive shaft 60. The roller 56 is grooved, as at I55 (Fig. 2), to receive the cutter I50. As the material M advances it is severed, as shown on the line B--B of Fig. 18, and after the longitudinal strands are removed, two pieces of tassel fringe F and F (Fig. 18) are completed.

Various modifications may be made within the spirit and scope of this invention and I intend no limitations other than those imposed by the following claims.

What I claim is:

1. Two sets of bending'and clinching dies disposed in substantial parallelism, means for actuating said sets alternately, means for moving material having parallel continuous edges stepby-step in a path normal to the paths of movement of 1 said dies to bring longitudinally and transversely spaced parts of the material intermediate the edgeS thereof alternately into alinement with the dies, whereby bindings are affixed to said spaced parts of the material, and means for severing the material longitudinally between said bindings.
